Yeah. Just as an example of a class specific gameplay issue, I'm a frost dk. With BFA we lost our AOE stun, our full heal, and our purge. Those three things were super fun and useful in M+, and now they're completely gone. It's fucking annoying.

A huge part of the slowness is because they had to invent a bunch of tech that doesn't exist yet, namely all of the procedural stuff. Now that a lot of that stuff is finished and they know what the vision of the game is, the rate of progress on the game is starting to exponentially increase.
